p IMPRQVBD METALLIC CHAIR-SEAT.

Be `it known that I, SI'LAs ALLEN SNYDnn, of Clarendon, in the county of Orleans and State of `New York,'have invented-certain Improvements in MetallicChair-Seats Orl-Bottoms, of which the following is i aspecilication.

`My invention relates to a new mode of constructing metallic seats,fand consists in forming the seat of sheet metal, having portions of its surface stamped or sunken, forming depressionsbelow the general surface,

in the manner and for the purposes hereinafter named. Figure l represents my improved chair-seat in plan Figure 2 isanenlargcd section of a portion of the seat and-frame,`on Jthe linea :vof tig. 1.

A is the ordinary frame, f wood, and B, the seat, forinedof suitable sheet metal, having the depressed portions da a stamped or otherwise impressed below the. general surface, and sunk to a uniform depth, as indicated by the dotted' line y, ig. .2.'

-flhese sunken `parts may be of any form or ligure l desired, as star-shaped, Octagon, or other geometrical iguresfand are preferably `made of ornamental form, thu's conserving taste and usefulness' at the same time. i

This seatY maybe .attached to the chair in any desirable lor convenient manner, and may consist of al'- most anysheet metal that is desired, as brass, zinc,

copper, tin, or rolnI the construction admitting of the l metal being used in very light and thin sheets, on account of the rigidity produced by the two planes wformed `by thc upper or unstamped metal andthe bottom surface ofthe sunkftigures, as is shown'in tig. .2. I am aware that metal has been used for seats of chairs, benches, Stel; andthat chairs,-.&c., have been constructed entirelyl of metal; and that patents have l beengranted for seatsofgrooved metal, andof corl rugated sheet metal, and. of woven wire, 'or wire-cloth, :or netting, and also Vof perforated sheet metal; and also that metallic stripsor ribbons have been woven -or interlaced like basket-workA for a like purpose.

The objection `inade to scatsof plain metal is, their smoothness'whichseats become so polished by use as to become inconveniently slippery and uncomfortable, Y

as well as unsightly.

t "The Schedule referred to these Letters Patentanc'l making part ofthe sanne.

The corrugated, perforated, slatted, or woven wire or ribbon surfaces are even more objectionable from the sharp and rough edges formed by punching or cutting the metal, rendering them uncomfortable to sit on, and subjecting to severe wear and abrasion the clothes of those using them.

I obviate these insuperable objections by my method of forming seats of sheet metal, with gures or portions depressed, as shown, below the surface, without puncturiug entirely through. This prevents all slipperyuess, and has an eminently pleasingeffect to the eye. It also gives sudeient uncvenness of surface to secure a stable seat, and renders` the metal more rigid,

thereby making a stronger seat, without leaving sharp, rough, or uneven edges, as is the case when the metal is punched, perforated, or cut in any manner, while I secure thereby an important advantage, in that the depressed portions may be painted or japanned of a 'color that forms an agreeable contrast to that of the metal used, .or` may be coated with noch, to imitate cloth or velvet, and these portions, from not being exposed to friction or wear, remain uninjured for a long time, and, as the general surface, which may be left unpainted, is kept brightby use, a pleasingl and desirable edect is thus obtained, in a simple manner, and ata small cost. This metal, gilt or silver-ed, would also make'a beautiful seat. .1

I further propose, for some purposes, as for a better class of chairs, totl'l the depressions with some composition which will be measurably elastic, as India rubber, rubber sponge, or moss rubber, thereby givinga degree of softness resembling a cushioned or up. h olstered seat.

As a new article of manufacture, a chair-seat having `parts or gures 'in intaglio impressed therein, substantially asand for the purposes set forth.

Inrwitness whereof I have herenntosigned my name in the presence of two subscribing witnesses. l

SILAS ALLEN SNYDER.
